Approval of systems of Biological Indication of Water Quality under the auspices of the Severn-Trent Water Authority, UK

In accordance with the plan for joint Anglo-Soviet scientific and technical collaboration on environmental problems, the comparative evaluation of systems of hydrobiological analysis of the surface water quality started in 1977 at the Regional Laboratory of the Severn-Trent Water Authority in Nottingham were continued in the spring of 1978. The investigations were carried out under the auspices of the Institute of Hydrobiology of the Academy of Sciences of the Ukrainian SSR. Hydrobiological and hydrochemical samples were collected by Soviet and British specialists from the Kiev reservoir and the rivers Dnieper, Sozh, Desna and Snov. The possible approved methods to be adopted were evaluated from the samples using the phytoperiphyton, phytoplankton, zooplankton and zoobenthos against a background of hydrochemical characteristics.

Biomassa dos principais recursos de peixe de Boa-Paz, Moçambique

Data collected during a survey conducted by the Soviet trawler Sebastopolsky rybak , in January 1987, covering the Boa-Paz area, Mozambique, were analysed. The biomass of demersal fish was found to be higher than the one of pelagic fish. The most representative group among the demersals was the first grade fish, where the families Sparidae, Lethrinidae, Lutjanidae and Serranidae were included, corresponding to a biomass of about 3,500 tonnes. In the pelagics the family Carangidae was the most important one and the species Decapterus russelli and Trachurus trachurus showed the highest biomass estimates in this family.

A Whale of a Deception

In late October of 1966, an imposing ship steamed quietly through the placid waters of the Suez Canal. Clad in drab industrial gray, and flying a Soviet hammer and sickle flag at her masthead, the vessel was accompanied by a large fleet of smaller craft. Any observer able to decipher Cyrillic script could have read, in rusting metallic letters on her bow, the name Sovetskaya Ukraina. The more experienced would perhaps have identified her as a whaling factory ship, traveling with her attendant fleet of catcher boats and scouting vessels on a transit that would take them south into the Red Sea and beyond.

A. A. Berzin and His Memoir

Alfred A. Berzin began to study whales in 1955 at the Pacific Research and Fisheries Center (TINRO) in Vladivostok where he is still working at the present time. In the years before the rapid development of Soviet whaling only two fleets (Aleut and Second Kuril) were hunting whales.
